【问题描述】：

我正在尝试使用以下命令编译MySQL++ 3.1.0：

mingw32-make -f Makefile.mingw

在一组文件被编译后（例如 beemutex.cpp、cmdline.cpp、connection.cpp、...），我收到以下错误：

g++ -c -o mysqlpp_sql_buffer.o -g -mthreads -DUNICODE -D_UNICODE -DMYSQLPP_NO_DLL -DHAVE_MYSQL_SSL_SET -I"C:\Program Files\MySQL\MySQL Server 5.5\include"   -MT
mysqlpp_sql_buffer.o -MFmysqlpp_sql_buffer.o.d -MD -MP lib/sql_buffer.cpp

我的配置可能有问题，但我找不到。找不到它似乎很奇怪，例如size_t。

谢谢！

平台：
视窗 7
MinGW 2011.09 / GCC 4.6.1
MySQL 5.5
mysql++ 3.1.0

【解决方案1】：

在refcounted.h 中将size_t() 更改为std::size_t() 解决了这个问题。它现在编译。

我仍然有链接问题，但它们应该是不同的问题。

【讨论】：

官方修复是#include <stddef.h>。这是自 MySQL++ 3.1.0 发布以来 GCC 更改所必需的。您可以通过从存储库而不是 tarball 获取 MySQL++ 来获得所有此类更改。它现在处于良好、稳定的状态，只是还没有达到我想要发布另一个版本的状态。
